lmllhll-lhllllll INVENTOR LOU/S HERMANN ATTORNEY States This invention relates to a swimminggpool construction and more particularly to a self-supporting rigid swimming pool construction formed of a plurality of-interlocking extruded metal sections.

The principal object of the invention is the provision of a swimming pool construction incorporating a plurality of interlocking aluminum extrusions to form the side walls of said pool. V

A further object of theinvent'ion'is' the provision of a swimming pool construction that may be used to form pools of various diameters and shapes and wherein the walls of the pools are formed of rigid aluminum extrusions having their longitudinal edges interlocked one with the other.

A still further object of the invention is the provision of a swimming pool construction comprising a plurality of interlocking vertically positioned extruded aluminum sections suitable for supporting a plastic liner to form a water-tight pool. r

A still further object of the invention is the provision of a swimming pool construction which forms a solid unbroken wall in a circular pattern which is ideally suited for supporting a plastic swimming pool liner.

The swimming pool construction disclosed herein comprises an assembly of extruded aluminum sections, each of which is identical and each of which has longitudinally extending interlocking formations on its opposite longitudinal edges. A plurality of such sections assembled in a circular or semicircular shape and provided with an inverted U-shaped plastic molding over their uppermost ends is ideally suited to support and contain a plastic swimming pool liner so that the same is protected from accidental or deliberate injury and at the same time is adequately supported to hold a sizeable volume of water whether the pool is constructed on the surface or below the surface of the ground.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all' changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure l is a perspective view of the swimming pool construction.

Figure 2 is an enlarged cross section of one of the aluminum extrusions from which the construction is formed.

Figure 3 is an enlarged horizontal section taken on line 33 of Figure 1.

Figure 4 is a perspective view of the swimming pool construction showing a modified upper edge structure.

Figure 5 is a perspective view of a bracket used with the structure shown in Figure 4.

" att st "Figure 6 is a vertical section through the upper edge of the structure shown in Figure 4 of the drawing, as taken on line 66.

By referring to the drawing andFigure 1 in particular it will be seen that the swimming pool construction 'is shown in assembled relation forming a circular pool through a plurality of vertically standing interengaging sections ltd-1'0. The extruded sections 1010are covered with a continuously extending inverted U-shaped member 11 which may be formed of plastic, as illustrated in Figure 1, but is preferably formed of rigid metal, as shown in Figures 4 and 6. The constructionmay be completely waterproofed by adding a vinyl or other plastic pool liner, as is known in the art. Alternately, the

pool. construction may be positioned on a concretelpad in an excavation with the upper ends of'the extruded sections 10-10 and member 11 located at approximate ground level and the construction waterproofed and used to directly contain the desired volume of water.

In Figure 2 an enlarged cross section of one of the extruded aluminum sections 101tl may be seen and it will be observed that on one longitudinal edge it is pro vided with a pair of oppositely disposed curving arrns'l'2 and 13 which form a circular shape of given diameter. The opposite longitudinal edge of the extruded aluminum section 10 has a similar pair of oppositely disposed curving arms 14 and 15 which are arranged in -a circular shape of a diameter larger than the diameter of the arms 12 and 13, heretofore referred to, so that continuous longitudinal engagement of an aluminum extruded section 10 may be accomplished with an adjacent identical aluminum section with the circular arms 12 and 13 on one extruded section engaged in the arms 14 and 15 of the adjacent extruded section.

In Figure 3 of the drawing portions of three of the extruded aluminum sections 10 may be seen in assembled relation, as upon line 33 of Figure 1, and it will be observed that the construction of the interlocking curving arms 12, 13, 14 and 15 is such that a relatively tight joint is obtained along the longitudinal edges of the extruded sections while at the same time a degree of flexibility is provided.

By referring to Figures 4, 5 and 6 of the drawing a preferred embodiment of the invention may be seen which is modified somewhat from the embodiment illustrated in Figure 1 and heretofore described. In Figures 4, 5 and 6 of the drawing the identically shaped extruded aluminum sections 10-41) are assembled to form a circular wall and the member 11 of Figure 1 of the drawing is replaced with a channel-shaped rigid metal member 16 which is formed in arcuate sections so that a plurality of such sections encircle the top of the circular wall formed by the assembled extruded aluminum sections 10, and which arcuate cross sectionally channelshaped members 16 are of a size suificient to enclose the complete upper edges of the several extruded sections 19. The channel-shaped members 16 are joined to one another at their adjacent ends and to the extruded aluminum sections 10 by a plurality of clamps 17 which are of inverted U-shape with depending arm portions 18 and 19. The clamps 17 are apertured as at 20 and threaded and receive bolts 21 therethrough. The bolts 21 are of sufiicient length to extend through registering openings 22 in the arcuate cross sectionally channelshaped members 16 so that the inner flanges of the members 16 will be forcefully engaged against the inner sides of the extruded aluminum sections 10 when the bolts are tightened inwardly ofthe clamps 17. The clamping action thus joins the adjacent ends of the arcuate cross sectional channel-shaped members 16 to one another while at the same time clamping the same The continuously joined plurality of arcuate cross sectlonally channel-shaped members 16 clamped to the upper edge of the extruded aluminum sections it) hold the aluminum sections 19 in vertical parallel position and prevent their deflection from vertical, as may otherwise occur.

The swimming pool thus formed has a uniformly level upper and lower surface and the vertical joints between the adjacent interlocked extruded aluminum sections 10 remain vertical at all times and prevent relative movement of the interlocked edges of the extruded aluminum sections 10.

It will thus be seen that the swimming pool construction herein disclosed provides a plurality of cut sections of identical extruded aluminum it; which are assembled in edge-to-edge relation in interlocking pattern, as hereinbefore described, to form a circular wall which is particularly suited for containing a sizeable volume of water, as necessary in a swimming pool,

The arcuate members 16, which are of inverted U-shape with a rounded out contour, are then positioned over the upper ends of the extruded sections it) and secured by the clamps 17. The vinyl pool liner is then installed and thepool filled.

The pool can obviously be quickly and easily assembled and disassembled when desired or it may be permanently installed in below or above ground relation, all as will occur to those skilled in the art.

It will be seen that the several objects of the invention have been met by the swimming pool construction disclosed herein.

.Having thus described my invention, what I claim is:

In a swimming pool construction including an assembly of a plurality of extruded sections, each of which has engaging formations on its longitudinal edges, the improvement comprising a plurality of arcuate cross sectionally channel-shaped rigid extruded members positioned in endto-end relation over the upper ends of said extruded sections and a plurality of inverted U-shaped clamps incorporating bolts securing said arcuate sections to one another and to said extruded sections and a waterproof swimming pool liner positioned in and supported by said swimming pool construction.
